Abstract
The invention discloses lever assembly before a kind of dual-pulling rod type of sewing machine, including preceding lever, preceding lever offers an axle position hole, and preceding lever can be swung by the centre of gyration of axle position hole；The swinging end of preceding lever connects the preceding nose end of the preceding nose end and short rod of long draw by bearing pin, and long draw and short rod can rotate rotating around respective preceding nose end；The rear nose end of long draw is connected with transmission parts, and the rear nose end of short rod is connected with rear lever.The present invention has the advantages that simple and compact for structure, convenient for installation and maintenance and transmission diversity.
Description
Technical field
The present invention relates to a kind of part of industrial sewing equipment, and in particular to lever group before a kind of dual-pulling rod type of sewing machine
Part.
Background technology
The preceding lever assembly of industrial sewing machine all employs the structure of a pull bar mostly at present, by pull bar preceding lever
Linked together with rear lever, realize the linkage of transmission, a kind of kind of drive can only be realized in this case.And present people couple
The automation of sewing machine and the diversity of operator scheme etc. require more and more, and the transmission mechanism of single formula also can not increasingly expire
The demand of sufficient people.
The content of the invention
The technical problems to be solved by the invention are to provide lever assembly before a kind of dual-pulling rod type of sewing machine, and it can be more
Add light, convenient solution problem above.
In order to solve the above technical problems, the technical solution of lever assembly is before the dual-pulling rod type of sewing machine of the present invention：
Including preceding lever 1, preceding lever 1 offers an axle position hole 11, and preceding lever 1 can be put with axle position hole 11 for the centre of gyration
It is dynamic；The swinging end of preceding lever 1 connects the preceding nose end 21 of long draw 2 and the preceding nose end 31 of short rod 3, the He of long draw 2 by bearing pin
Short rod 3 can rotate rotating around respective preceding nose end；The rear nose end 22 of long draw 2 is connected with transmission parts, short rod 3
Nose end 32 is connected with rear lever 5 afterwards.
The preceding nose end 21 of the long draw 2 is sheathed on bearing pin jointly with the preceding nose end 31 of short rod 3, before long draw 2
Separated between nose end 21 and the preceding nose end 31 of short rod 3 by jump ring 4.
The preceding nose end 21 of the long draw 2 is circular hole, and the rear nose end 22 of long draw 2 is long groove shape.
The preceding nose end 31 of the short rod 3 is circular hole, and the rear nose end 32 of short rod 3 is circular hole or long groove shape.
The middle part of the long draw 2 is formed with bending part.
When transmission parts drive the rear nose end 22 of the long draw 2 to be swung around its preceding nose end 21, can drive simultaneously before
Lever 1 is swung；Or when rear lever 5 is swung, lever 1 is swung before being driven by short rod 3, and drives long draw 2 to move.
What the present invention can reach has the technical effect that：
The present invention has the advantages that simple and compact for structure, convenient for installation and maintenance and transmission diversity.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description, those skilled in the art
Other advantages and effect thus, it is possible to be better understood by the present invention.It should be noted that the knot that the accompanying drawing of specification is drawn
Structure, ratio, size etc., only to coordinate embodiment, the structure of the present invention is better understood upon for those skilled in the art
Think.

Embodiment
As shown in Figure 1 to Figure 3, lever assembly before the dual-pulling rod type of sewing machine of the present invention, including preceding lever 1, preceding lever 1
Middle part offers an axle position hole 11, and preceding lever 1 is connected on casing 100 by the axle of axle position hole 11 and can be with axle position hole 11 for revolution
Center is flexibly swung；
A wherein swinging end for preceding lever 1 connects the preceding nose end 21 of long draw 2 and the preceding nose end of short rod 3 by bearing pin
31, the preceding nose end 21 of long draw 2 and the preceding nose end 31 of short rod 3 are sheathed on bearing pin jointly, and the preceding nose end 21 of long draw 2 with
Separated between the preceding nose end 31 of short rod 3 by jump ring 4；Long draw 2 and short rod 3 can be flexible rotating around respective preceding nose end
Rotate；
The rear nose end 22 of long draw 2 is connected with transmission parts, and the rear nose end 32 of short rod 3 is connected with rear lever 5.
The preceding nose end 21 of long draw 2 is circular hole, and the rear nose end 22 of long draw 2 is long groove shape.
The preceding nose end 31 of short rod 3 is circular hole, and the rear nose end 32 of short rod 3 is circular hole or long groove shape.
The middle part of long draw 2 is formed with bending part.
When transmission parts drive the rear nose end 22 of long draw 2 to be swung around its preceding nose end 21, lever 1 can drive simultaneously before
Swing；
Or when rear lever 5 is swung, lever 1 is swung before being driven by short rod 3, and drives long draw 2 to move.
Specific implementation example above, to protection scope of the present invention and is not limited in any way, and every use equally is replaced
Change or equivalent transformation formed technical scheme, within protection scope of the present invention.
